I would know the Moon's Age May the 12th, 1736; the Epact is 28, then the Sum of 28 and 3 and 12 is 43 ; subduct 30, the Re. mainder shews the Moon to be then 13 Days old; wherefore on the 14th of May will be the Full Moon ; and 15th before, viz. 29th of April, the Moon chang'd.

This was finish'd and first publish'd in the Year of our Lord 457. Afterwards, in the Year 527, Dionysius Exiguus, a The Dionysian Roman Abbot, corrected it in fome Particulars, Period. and it was calld the Dionysian Period from him ; as also the Great Paschal, because the Western Great Paschal. Churches went by it for many Ages, till Pope Gregory XIII. new modeld it, as before related.

He supposed the Excess of the Solar Year above the Lunar at the End of the Metonic Cycle of 19 Years, would in the Course of 4 of those Cycles, or 76 Years, amount to a whole Day, and so cast away a Day in every such Period of 76 Years. But herein he was greatly deceiv'd, for the Excess of the Solar Its Defeet. above the Lunar Year in one Cycle is but is Hour, and therefore in 4 Cycles, or 76 Years, could amount to but 6 Hours instead of 24. Wherefore the Error of this Period is a Defi. ciency of 18 Hours nearly. of Hippar- This gave Occasion afterwards to Hipparchus chus's Period. of Nicea in Bithynia to make a new Correction of the Metoric Cycle ; for he observing that the many Ages after. of the Cycle of The Romans made use of a Cycle, call’d the Indition, Cycle of Indićtion, which had no Relation to the Celejial Motions, but was used for Civil Purposes, the chief of shich was to indicate or make known the 304 Years ; the Time of certain Payments made by the Roman Subjects to the Republic. It consisted of 3 Lustrums, or 15 Years ; and was establish'd by Constantine, A. D. 312, in the Room of the Greek Olympiads. To find the Year of this Cycle, fub.

From the Multiplication of the Cycles of the of the Julian Period. Sun, Moon, and Indication arises the famous Period, callid the Julian Period from Julius Scaliger the reputed Author thereof. This Period consists of 7980 Years, (for 28 by_19 gives 532 ; and that by 15 gives 7980.) This Period had its Beginning fix'd to the 764th Year before the Creation, and is not yet compleated ; and therefore comprehends all other Cycles, Periods, and Epochas, and the Times of all memorable Aitions and Histories. There is but one Year in the whole Period that has the same Numbers for the three Cycles of which it is made up : And therefore if Historians had remark'd in their Annals the Years of the respective Cycles, there had been no Dispute about the Time of any Action. The first Year of Christ was the 4714th Year To find the Year the cof. of the Julian Period ; and therefore if to the current Year of Chrijt we add 4713, the Sum will be the Year of the Julian Period.
